声表面传感器和磁弹性传感器对气体定量检测的比较研究

随着社会的工业化进程加快,机动车、电厂废气等人为因素产生的NO2日益增多。NO2虽然对臭氧的形成有重要作用,同时也会导致酸雨的形成,所以检测NO2的浓度在很多领域有着重要意义。本文以NO2为检测对象,对其不同频率响应采用两种传感器进行初步实验并进行比较分析,声表面波传感器是利用沿着物体表面传播的弹性波来感测信号的,而磁弹性传感器是由外加磁场对磁弹性材料的作用来感测信号的,两种传感器的响应信号都是频率偏移,在实验中,传感器的频率响应采用网络分析仪测试。实验结果表明,磁弹性传感器相对于声表面传感器对NO2的吸附前后频率响应更明显,对相关领域的研究更具实际意义。     

Forecasts in IPO Prospectuses: The Effect of Corporate Governance on Earnings Management

Prior research suggests that managers may use earnings management to meet voluntary earnings forecasts. We document the extent of earnings management undertaken within Canadian Initial Public Offerings (IPOs) and study the extent to which companies with better corporate governance systems are less likely to use earnings management to achieve their earnings forecasts. In addition, we test other factors that differentiate forecasting from non‐forecasting firms, and assess the impact of forecasting and corporate governance on future cash flow prediction. We find that firms with better corporate governance are less likely to include a voluntary earnings forecast in their IPO prospectus. In addition, we find that while IPO firms use accruals management to meet forecasts; the informativeness of the discretionary accruals depends on whether or not the firm would have missed its forecast without the use of discretionary accruals.     

Institutional impact on the expropriation of private benefits of control in North Africa

This paper examines the effectiveness of six institutional quality measures, namely corruption control, effective government, political stability, regulatory quality, rule of law and voice and accountability, in inhibiting self-rewarding behaviour of boards in terms of their compensation as well as in influencing the likelihood of disclosure of individual executive salaries in IPO listings prospectuses. Using a unique and comprehensive dataset of 78 hand-collected IPO firms from across North Africa from 2000 to 2012 I find substantial evidence that government effectiveness and corruption control are important in inhibiting director self-reward and expropriation while political stability is more associated with increased likelihood of transparency in reporting of salaries. In addition firms from poor informational environments are more likely to initiate enhanced self-governance and transparency so as to overcome institutional deficiencies.     

The IPO of Industrial and Commercial Bank of China and the ‘Chinese Model’ of privatizing large financial institutions

We examine the privatization process of the Industrial and Commercial Bank of China (ICBC), the largest bank in the world by market capitalization, and its dual initial public offerings (IPOs) in the Hong Kong and Shanghai Stock exchanges in 2006. The Chinese government retains majority equity ownership of ICBC while foreign institutional investors hold minority equity stakes. Other large financial institutions went through the same reform process and have similar, post-IPO ownership structures. The largest Chinese banks, as a group, outperformed their counterparts from other emerging and developed markets before and during the 2007–2009 financial crisis. We argue that the ‘Chinese model’ of privatizing and managing large financial institutions can be advantageously used in other countries.     

浅析新会计准则对证券金融企业的影响

2006年2月,我国新会计准则体系出台,所有上市公司将于2007年1月1日起开始执行新准则.新准则的出台给我国各行业的会计实务界带来了巨大的挑战.新会计准则中和金融业相关的有:《企业会计准则第22号--金融工具确认和计量》、《企业会计准则第23号--金融资产转移》、《企业会计准则第37号--金融工具列报》.随着我国证券市场的进一步发展,证券公司谋求上市的步伐越来越快,市场对证券公司对于会计准则的研究理解掌握程度的要求也不断的提高.本文通过分析新会计准则对证券公司的影响,指出在新制度环境和市场环境下券商的发展所将要遭遇的问题及对策,为券商提高财务管理水平,增强竞争能力,提供一定的借鉴意义.     

论中小企业美国上市的方式选择

国内很多中小企业试图通过海外上市获得资金支持。而美国资本市场反向收购由于其时间短、成本低、成功率高等特点，越来越受青睐。本文通过详细介绍美国资本市场反向收购的相关知识，以期为国内企业海外上市指明方向。     

警惕我国核准制下IPO阶段舞弊之风险

20 0 1年3月1 7日,中国上市公司(theListedCompanyinChina)的股票发行(stockissue告别了额度制,开始实行核准制。经过3年的实践证明,核准制对上市公司发行新股(IPO)阶段舞弊行为的监控(monitor)是得力的,至少目前尚未有关于此方面的负面报道。但美国HPL公司舞弊一案却给我们敲响了警钟。舞弊行为在高科技运用方面已有纵深突破趋势,单靠核准制能否杜绝IPO阶段舞弊发生令人忧虑。因此未雨绸缪,我们必须提高警惕并积极防范     

股票发行违规、撤销制度与投资者保护分析

从2000年红光实业的处罚,到2002年的通海高科"曲线"上市,再到2009年立立电子否决案,不仅反映了我国相关证券监管法律与制度的完善,对中小投资者保护力度的提高,还体现了管理层改革完善股票发行制度的决心。由于目前我国的《公司法》与《证券法》并未对上市之后发现上市申报材料造假的情况予以相应的规定,如果造假发现在公司上市之后,中小投资者的利益将很难得到保护。     

核准制下IPO价格行为的比较研究

我国核准制包括通道制和保荐制两个阶段,IPO价格行为包含IPO抑价和IPO长期表现失常两个过程。文章对我国核准制下IPO价格行为的表现及影响因素进行了实证分析,结果表明：核准制两个阶段的IPO价格行为区别明显,保荐制下IPO抑价率与三年累计超额收益均低于通道制;通道制主要受到市场和行政发行方式等外部因素影响,保荐制则主要受到发行公司自身规模和财务状况等内部因素的影响。这些现象说明,保荐制的实施提高了新股发行定价效率,保证了上市公司的质量,使投资者的行为更加理性。     

从诗化形式看《海浪》的整体性构建

传统小说的整体性是通过时间、地点和情节来构建的,而意识流小说没有完整意义的情节,没有逻辑发展的戏剧性事件,物质时间的作用弱化,被淹没在人物意识流动所构成的心理时间的延展之中,不足以构建小说的整体框架。伍尔夫的《海浪》是其意识流小说的巅峰之作,体现了她"诗化小说"的创作倾向,运用诗歌中的韵律和意境,通过六个人物的内心独白实现了意识流小说的整体性构建。
